Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74842, here are decompositions:

11 + 74831 = 74842
71 + 74771 = 74842
83 + 74759 = 74842
113 + 74729 = 74842
233 + 74609 = 74842
269 + 74573 = 74842
281 + 74561 = 74842
311 + 74531 = 74842

Showing the first eight; more decompositions exist.
